The Schedule referred to in `these Letters Patent and making part of the same.

JOB ABBOTT, of Dexter, in the county of Penobscot and State of Maine, have made anew and useful'invent-ion, having reference to theY Covers of Culinary- Boiiers,--Dye-Vats, and various other vessels; and do herebydeclare the same to be fully described in the following specification, and represented in the accompanyingdrawmg, which is a vertical section of a boiling vessel. with my steam-discharging` and deviating cover applied thereto. In suchdrawing I A -A` denotes the vessel or boiler, and

B, itis cover, the latter being in-fthe form of a hollow conic frustum,' and made to closely fit tothe top of th'e boiler.

An inclinedv 1iange,a, arranged varound theV inner 5s|1'1'face` cfvthecover, and just over the top of the "vesselvfA, serves to intercept any `condensed steam whenflowing down `the inner surface of the cover, and'to convey ordirect it into the vessel.

` Atthe tcp the' coverjis provided with a'tube or conduit, '13', which opens out of the cover, and at top lprojectsfa short distance into another tube, C, lead- :ingtoachimney or discharge-flue.

within A the cover, lor regulate itsl escape therefrom, as Circumstances may Trequire.

The cover B is 'suspended to the tube C by means f`ofV counterbalance Weights, b `b, appended-to cords or ehainsc c, cam'ed around'sheaves or pulleys dd, supported in brackets e-e,'sucl1 brackets being projected ii'om 'the tube-1G. l

nthe lower part of ftheconduit B' is a damper or 1turuingfvalve,`1),itspurpose being to retain the steam Over thevmouth or upper end of the tubeB isa flange or deflector, f, which is arranged in and' around the tube C, so as to discharge into the tube B'any I steam which may be condensed onlthe inner surface of such tube C.

The tube G may extend into the tube B', but this .Y is not so good' an arrangement as that `hereiubefore' described.

The opera-tion of the mov, ble cover will be readily understood'. It may be raised on" the boiling vessel,'; and, while on it, will serve to retain ythe steam or dis-'. charge it therefrom; as may be requisite.; Y I The-invention is'specially .applicable to dye-vat covers, where it is particular useful and advantageous \Ve make no' claim to anything descrlbedln the United States Patent granted September 26, v1335,@ Ezekiel Daboll.
